Believe it or not, NPH could be the closest to what you're looking for. Are you looking for something to cover basal needs, or something to bolus/correct with?

NPH peaks at 4-7 hours (you need carbs to cover about half the injected amount of insulin) and lasts 10-14 hours. About half of the injection has a basal effect which is spread over that time.
Regular is a bolus insulin, which peaks at 2-3 hours and lasts 5 to 8 hours. So it has an even bigger "peak" than NPH - she would have to eat considerable carbs to cover an injection, with much less basal effect.
